TILE-PAVEMENT.

SPIiCIPIQATION forming part of Letters Patent No, 347,851, dated August 24, less.

Application filed uiy 28,1885. Serial No '173,l97. (No specimens.)

To all whom it may concern i Be it known that I,.EDWARD H. BARRETT, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State 5 of Minnesota, have invented certain Improvemeats-in Tile-Pavements, of, which the follow ing is a specifi'cation.-

My invention relates particularly to inn-- provements in pavements or doors for public and-private buildings, and especially to floors for corridors, halls, and vestibules. Hereto-' fore these floors have often been composed of tiles of marble and slate; and itis the object of my invention to. provide a-fl0or-tile that 5 shall form a floor having the appearance largely of a tile-floor of marble and slate, but which I shall be bothfcheaper and more durable than the marble and slate fioor,'and capable of tak- I ing a'higherdegree of polish. 2o

In carrying out my invention I manufacture a tile that is composed of cement and other materials, and'with this "tile I lorm all kinds of inside pavements or floors.

In making ti '8 tile I take the following in- 'gredients or materials in about the proportions I 0 mixed. I then make a mixture of alum, onespeeified, to wit: French or Portland cement, four parts; pulverized ram e, wo pars; crushed jas )er two parts; Iiue silicious sand ese materials are thoroughly one pa halfpound; ses uioxide of iron, three pounds; arbonate oi o asli, twopounils,1n fifteen gallens of water. '.[he mixture of cement and other materials above-mentioned are then 5 thoroughly incorporated with this second mixture, and the whole is mixed or combined by v tamp or mac me. 1 composition is then made into tiles of any desired form or size by being placed in suitable molds and subjected 0 to powerful pressure until completely united. i The tiles are then removed from the molds and submerged in a warm bath of silicate of soda or glass ese 1 es, whentof sufficlent age, become very hard, possessing in a large degree the 5 properties of'granite, and like granite being capable of taking a highly-polished surface.

In making floors I'generally lay a foundation composed of cement and sharp clean sand, dampened --with water. This foundation is v tamped down and its upper surface is made level and smooth.- \Vhile the base-isstilldamp I lay the tiles thereon and press them down solidly onto but not into the base, thereby making a firm and solid floor. All of the tiles .for any floor are of uniform thickness.

These tiles mayb'e'made of any'desired color, and of rectangiilar, hexagonal, .or other shape.

I claim as my inventioni v 1. A floor-tile composed of cement, granite, jasper, and sand, substantially as described.

-2. A door having a 'tamped foundation of cement and sand and a layer of cement tiles pressed firmly down on said foundation, substantially as described.

3. The within method of forming a floorsaturating said mixture with a mixture of alum, sesquioxide ofiron, and carbonate of Examiner tile-consisting in first mixing cement, phlver-- 'ized granite, crushed jasper, and sand, then potash, then molding the mixture and al't'erwards sub'merging the tile in a warm bath of silicate of soda or glass, substantially as de;

scribed. I

4. The within method of forming afioorized granite, crushed jasper, and sand,'then incorporating said mixture with alum, sesqui oxide of iron, and carbonate of potash, and

then molding the composition, substantially,
